Yeah, there is this irq-work in v5.10-RT and this slightly different
thing that managed upstream while upstream managed to alter their code,
too  :)

Please find attached as a reply to this email the backported patches:
   [PATCH RT 1/3] irq_work: Allow irq_work_sync() to sleep if irq_work() no
   [PATCH RT 2/3] irq_work: Handle some irq_work in a per-CPU thread on
   [PATCH RT 3/3] irq_work: Also rcuwait for !IRQ_WORK_HARD_IRQ on

which apply here on top of v5.10.78-rt55.
